Answer:
X is the quantity value
Explanation:
To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. Then the standard deviation of X is the quantity. (derived using the properties of expected value). In other words, the standard deviation σ (sigma) is the square root of the variance of X; i.e., it is the square root of the average value of (X − μ)2.

Essentially, multicellular organisms are made up of more than one cell. As such, they are different from unicellular (single celled) organisms that only consist of a single cell. Like unicellular organisms, there are a wide range of plant and animal multicellular organisms in existence.
